I think this is a defect of Sqoop, and opened a jira for it: https://issues.apache.org/jira/browse/SQOOP-1164. I set the priority as Minor, because it has the workaround: only leave the target driver jar file in the sqoop/lib folder, but remove other driver jar files from the folder. However, it should be mentioned that when we have many dirver jar files under sqoop/lib folder for multiple kinds of databases, or a script will connect to different databases, this workaround can not work well.
